The trouble I see with sales tax is that it rubs the tax in the face of each purchasing consumer at the point of purchase. There are people who will see that the taxes go to pay for our infrastructure and that is the price we pay for a civil society, but there is a very large group who will not see that, They will focus on the added charge to the bill in front of them and they will freak. they are typically democrats BTW.
An excise tax, on the other hand, we have had for over 200 years and is a much more digestable tax for the average citizen. Everyone knows at some level that there are large taxes on liquor, but nobody has the fact that the liquor bottle they are buying for $20 has about $18 in taxes in it. People have gotten used to the tax, they don't object too loudly to it and life goes on.
If you want to focus on a sales tax as the method, it will work and everything said in that video is true, except that it will never get beyond a pep rally of republicans, because the democrats will kill it every time.
I just want to be practical, and maybe see motion towards this concept before the parasitic losses to taxes destroys my kids America.
